Suppose y varies directly with x. if y = -4 when x = 8, what is the equation of direct variation? complete the steps to write the equation of direct variation.1. start with the equation of direct variation y = kx.2. substitute in the given values for x and y to get3. solve fork to get4. write the direct variation equation with the value found for k. the equation is

(05.02)a farmer has decided to divide his land area in half in order to plant soy and corn. calculate the area of the entire area so he knows how much soil is needed. a parallelogram with a height of 6 yards and side length 9 yards. the height forms a triangle with the slanted side of the rhombus with a base of 2.5 yards. rhombus is split into a soy half and a corn half. each bag of soil covers 40 square yards. how many bags should the farmer purchase?
